T0 to whom it may concern: j

Be it known that I, EDWARD G. DURANT, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Machines for Ornamenting Blocks, Tiles, 850., of which the following is a specification.

My invention relates to an improvement in machinery for ornamenting clay or other plas-' tic material, which is molded into solid orhollow form.

The invention consists in the combination,

' with such a machine, of a roll or rolls located at a point near the discharge-outlet of the machine in such manner that after the material has been partially shaped it is brought into contact with the roll or rolls to receive a further finish, which may be smooth or figured,

as desired. It the article being produced is hollow, the core over which it is formed will need to be extended to such point as is necessary to form a support while the material is being operated upon by the roll, and the outer casing should also be extended so that the pressure of the roll may not injure the form of the article. The roll or rolls may be actuated by merely coming in contact with the moving mass of material being molded,

or they may be actuated positively my gearing or belts, or in any other equivalent manner. The number of the rolls will be varied,

according as to whether it is desired to ornament one or more faces of the molded article, and should be so applied to the machine as to be capable of ready application, removal,

and adjustment.

In the accompanying drawings, Figure l is a perspective view of so much of a machine as is necessary to illustrate the application of my invention; Fig. 2,a similar view showing the appearance of the molded article as it emerges from the machine, and Figs. 3 and 4 are sectional views through the former or discharge outlet of the machine.

A indicates the outer casing or shell of the delivery spout or former, and B the core, which will be used in connection with the said casing or shell when the machine is designed for producing hollow articles.

I do not wish to be understood as limiting myself to any-particular form or construction of the former, as it is obvious that the latter Will be varied according to the form in crosssection of the article to be produced, and will also vary in the different machines now in use.

In one or more faces of the casing or shell A, I form openings ct, through which the ornamenting-surface of the roller 0 projects, as more clearly illustrated in Figs. 3 and 4:, the said roller being carried by arms B, which may be slotted, as shown in Figs. 1 and 2, to permit the adj ustmeut of the roller toward and from the material being operated upon, in order that the ornamentation may be varied in depth. The number of these rollers may obviously be varied, as desired, so as to act upon one or more faces of the material being molded.

Upon reference to Fig. 3 it will be noticed that the working-face of the roller projects slightly beyond the inner face of the casing or shell A, so that as the material passes between the shell and the core it will act upon the roller and cause the latter to rotate, and in thus rotating to impress upon the clay the desired ornamentation.

It will be noticed that the material is supported at a point directly opposite that on which the roller acts and also on the other sides, so that in impressing or indenting the clay the shape of the article as a whole will not be changed or modified in any way whatever. Indeed it will be found advantageous in some cases to make the surfaces of the rollers perfectly smooth, in order to repress the material and prevent the formation of streaks in the material,besides condensing it and destroying the laminations.

WVhen it is desired to use the rollers upon machines making or producing solid articles, of course the core will be omitted.

It is clear that by reason of the rollers acting upon the material while it is confined within its former considerable more pressure can be applied to the material than would be the case if the rollers were arranged in position to act upon the material while unsupported.

In Fig. 3 the supporting arm or arms for the roller are shown as cast upon the shell or casing A, and when this construction is adopted it will be advisable to provide the arms with elongated slots, in order that the roller may IOC be adjusted, so as to press with greater or less force upon the material. The action of the rolls, as before stated, tends to condense the outer face of the block or other article being produced, and renders the same more impervious to dampness than would be the case if the block or material were not so compressed.

Having thus described my invention, what I claim is 1. In combination with a tile, brick, or pipe machine, a roller applied to the former or discharge outlet of the machine and adapted to act upon the material while supported by the former.

2. In a machine for producing pipe, tile,

brick, and similar articles, the combination, with the former, of a roller or rollers projectin g through the wall thereof and adapted to bear upon the material passing therethrough.

3. In combination with the former A, having an opening or openings in its wall, a core 13, located within the former, a roller working" through the opening; or openings in the former, and means for supporting said roller.

In witness whereof I hereunto set my hand in the presence of two witnesses.
